I think it depends on the turf, I have some offcuts from when next door did his garden lawn and that stuff is still fresh green after 3-4 years in his garden and the bits mine plus being in full sun all day. I also have some cheepo Lidl stuff that has weathered with dirt but not gone blue but has attracted some moss in places that makes it look more acceptable. But yes would never turn my lawn into artificial stuff, not so good for the dog and let us not mention what dogs do on grass! But yes nextdoor does have to weed his artificial stuff, but for many getting older I can see the attraction of not having to cut grass every week in the season but do agree with the bugs and miniature organisations sentiments. Below from next door.Can I please tentatively suggest you rethink about your artificial grass? It does last very long, and sunlight causes it to turn blue in a few years! It's also not environmentally friendly, as it stops the bugs from doing whatever bugs do, and no bugs, everything goes to pot. I know a lit of people use it, and it obviously negates the need for mowing, but it will still need weeding, and the weeds will be deep rooted jobs that will be a b*gg*r to remove
